How do Lab-Scale Centrifuges Work?
Sedimentation principle: a necessity for laboratory experiments and a blessing for life science researchers
The separation of unwanted material from your test sample is a critically important step in biological experiments. One of the most common and easiest methods for achieving this separation is the use of a centrifuge. Centrifuges use a rotor to spin liquid samples at very high speeds around a fixed center. The acceleration causes the constituents of the sample to be separated based on differences in their sedimentation properties.
The sedimentation principle is applicable from particles down to the nano-scale and molecules of different masses, resulting in the heavier material being forced to the bottom of the centrifuge tube, increasing the purity of the processed sample.
Centrifuge Applications within the Laboratory
In life science research, centrifuges are used extensively in numerous types of laboratory experiments. In cell culture, they are employed when separating cell-lines from spent media, and in DNA and RNA isolation procedures they aid in the separation of DNA/RNA from cellular debris. The type of centrifuge will vary depending on its application and desired result of centrifugation steps.
At ZAGENO we offer a wide range of research centrifuges. Our marketplace’s product portfolio holds large floor centrifuges as well as micro-centrifuges, all of which are suitable for your sample processing and day-to-day laboratory needs. Compare centrifuges based on key attributes such as rotation speed (rpm/rounds per minute), g-force, size, and capacity.
Check out our catalog of laboratory centrifuges and centrifuge equipment from leading life science brands: Eppendorf International – Laboratory equipment, supplies & services and among others the centrifuge specialist Andreas Hettich GmbH.

Types of Laboratory-Scale Centrifuges you can Purchase on ZAGENO
Benchtop centrifuges are a common type of centrifuge in the lab. They work with or without refrigeration and spin at low to mid speeds (up to 4000 rpm). They are common in clinical labs and are a necessity for cell culture and microplate processing.
Microcentrifuges are used in biochemistry and molecular biology laboratories for the separation of sample volumes ranging from 0.2 ml to 2 ml. They can generate forces up to 15,000 x g and are commonly used for genetic extraction experiments. We offer top of the range microcentrifuges that are compact, versatile, safe and easy to use.
High-speed centrifuges spin at up to 15,000 – 20,000 rpm. They usually are refrigerated and can handle larger sample volumes ranging from milliliters to several liters.
